One"portion of the equalizing cable 39 extends around sheave 40 and to theleft as at 44 in Fig. 2, while the other end extends around sheave 41and to the right as at 45 in Fig. 2. The connector 38 has spaced fingers38a and 38?) which are capable of limited rocking "movement around theupper end of the spring as a center.

The under side of the lay at the left end as viewedin Fig. 2 has securedthereto a pair of brackets 46 and 47 on which are mounted for rotation,respectively, sheaves 48 and 49. A cable 50 is attached to the end 44 ofthe equalizer 39 by means of a connector 51 having spaced fingers 51aand 51b capable of moving around the end 44 of cable 39 as a center. Oneportion of said cable 50 extends from the hook eye 51 around the sheave49 and is attached to a pin 52'carried by a small bracket 53 secured tothe backstay 13. The other side of the strand 50 extends around sheave48 and is connected to another pin 52 in another bracket 53 also rigidwith respect to the backstay.

In like manner on the right end of the lay as viewed in Fig. 2 a secondcable 54 has connection with the end 45 of cable 39 by means of aconnector 55 having fingers 55a and 55b to engage cable 54 at two spacedpoints. One side of said cable 54 passes around sheave 56 mounted inbracket 57 on the under side of the lay and is attached to a reed pin52. The other side of cable 54 passes around sheave 58 mounted forrotation in a fourth bracket 59 on the under side of the lay and isconnected by means of the fourth pin 52 to the backstay. The pins 52 andtheir brackets 53 filling to be beaten into the cloth and any yieldingwhich is rendered necessary during this operation will be permitted bythe single spring 36 acting through the ends of the cables 50 and 54attached to the several pins Should the let-off hesitate in its motionand create excess tension in the warp threads the reed will encounterabnormally high resistance but this will be evenly distributed becauseof the fact that the cables 50 and 54 are capable of slipping through.their respective hooks and also strand 39 is free to slide through itshook 38. Also, if it be desired to increase the resistance offered bythe reed when a heavier grade of cloth is being woven the winged nut 37may be operated to lower the eye 32, thereby increasing the pull whichis exerted by the spring 36 on the several pins 52.

Having thus described my invention it will be seen that changes andmodifications may be made therein by those skilled in the art withoutdeparting from the spirit and scope of the invention and 1 do not wishto be limited to the details herein disclosed, but what I claim is 1. Ina lay for a loom, a reed movable with respect to the lay, a singleresilient element, and means acting in tension to operatively connectsaid element to the reed at a plurality of different points along thelength of the reed, said element acting through said means to otterequal degrees of resistance to movement of the reed with regard to thelay at all of the points.

2. In a lay for a loom, a reed movable with respect to the lay, a singleresilient element, a flexible device connected operatively to the reedat a plurality of points along the length of the reed, and means toconnect said device operatively to the single resilient element to causesaid element to offer resistance to the movement of the reed withrespect to the lay at each of the points of operative engagement betweensaid reed and the flexible device.

3. In a lay for a loom, a reed movable with respect to the lay, a singleresilient element, a plurality of connected flexible members one ofwhich is operatively connected to the re silient element and the otherof which is operatively connected to the reed at a plurality of pointsalong the length thereof to offer resistance to relative movement of thereed with respect to the lay by a force derived from the said resilientelement.

4. In a lay for a loom, a reed movable with respect to the lay, a singleresilient element, a system of flexible devices connected to the reed ata plurality of points along the length thereof, and means to connectsaid devices to the resilient element, the latter offering resistancethrough each of the devices to movement of the reed with respect to thelay.

5. In a lay for a loom, a reed movable with respect to the lay, a singleresilient element, a flexible device operatively connected to the reedat a plurality of points along the length of the latter, and anequalizer interposed between said device and the resilient element. thelatter acting by a. force transmitted through and distributed by theequalizer to offer substantially the same resistance to relativemovement of the reed with respect to the lay at each of the points wherethe flexible tive connection with the flexible members,

said equalizer insuring the transmission of forces of uniform magnitudefrom the resilient element to the reed at each of the points where thelatter has operative connection with the flexible members.

7 In a lay for a loom, a reed movable with respect to the lay, a singleresilient element, and an equalizer operatively connected to the lay ata plurality of points and located intermediate the ends of the reed andconnected to the resilient element, the latter acting through theequalizer to yieldingly resist movement of the reed with respect to thelay at each of said points.

8. In a loom lay having a lay sword, a single resilient element mountedon the sword, and a flexible equalizing device operatively connected tothe resilient element and the reed to oiier substantially the sameyielding resistance to relative movement of the reed with respect to thelay at a plurality of points along the length of the reed.

9. In a loom lay having a reed movable with respect to the lay andhaving also a lay sword, a single spring supported by the lay sword, andan equalizer interposed between the spring and a plurality of spacedpoints along the length of the reed, said equalizer offering yieldingresistance in substantially equal amounts at said points to movement ofthe reed with respect to the lay.

10. In a loom lay having a reed movable with respect thereto, aresilient element, an equalizer interposed between the resilient elementand a plurality of spaced points along the length of the reed, saidequalizer transmitting the yielding force of the spring and resistingmovement of the reed at the said points with respect to the lay byforces which are substantially the same for all of said points.

11. In a loom lay having a reed movable with respect to the lay, asingle resilient device, and means acting in tension and interposedbetween said device and the reed at a plurality of points along thelength of the reed to ofier substantially the same resistance to themovement of said reed with respect to the lay at all of the said points.

12. In a loom lay having a reed movable with respect thereto, a singleresilient device,

sheaves mounted on the lay for rotation with respect to the latter, aflexible element movable around said sheaves and having operativeengagement with the reed at a plurality of points, and an equalizerinterposed between said flexible element and the resilient device andtransmitting a yielding resistance offered by the device to the elementand insuring substantially the same resistance being offered to therelative movement of the reed with respect to the lay at all of saidpoints.

13. In a loom lay having a reed movable with respect thereto, a singleresilient device, and equalizer means to operatively connect said deviceto the reed at a plurality of points along thelength of said reed and toinsure the transmission of resisting forces of substantially the samemagnitude from said device to all of said points.

14. In a loom lay having a reed movable with respect thereto, a singleresilient device, and equalizing means to connect said deviceoperatively to a plurality of spaced points along the length of thereed, whereby said single resilient device oil'ers uniform resistance tomovement of the reed with respect to the lay at a plurality of pointsalong the length of the reed.

15. In a loom having a lay with a reed movable with respect thereto, asingle resilient element, a pair of separate devices one connected toone portion of the reed and the other connected to another portion ofthe 'reed, and an equalizer interposed between said device and theelement and effective to cause said element to ofier equal degrees ofresistance to movement of the various points of the reed with respect tothe lay.

In testimony whereof I have hereunto affixed my signature.
